This thread has been discussing an obscure condition where the two Principals do not both have their joint Marriage tag marked Primary. There is a concept of entering Marriage tags which will almost always ensure that TMG will automatically mark both Principals as Primary. The concept is that when you add a new Marriage tag, always link both Principals as part of the creation of that tag. Don't add and exit creating the tag with only one Principal assigned. There are two data-entry practices which will accomplish that. A- Ensure both spouses are added to the database BEFORE you add their Marriage tag. Then you can assign both spouses either by directly entering their IDs or using the Picklist as part of adding that new tag. B- If one spouse is not yet added, begin to add the Marriage tag to the existing spouse. But BEFORE you OK out of that new tag, put your cursor in the ID number field of the "other" spouse and click the "Add Person" icon in the upper right of the Tag Entry window of this new Marriage tag to add the other spouse. Once that spouse is entered, you can now finally OK out of creating the new Marriage tag. Either method will aid TMG in ensuring appropriate settings for Primary. Hope this helps, Michael P.S. There are still ways the Primary settings could become non-symmetric, including inadvertently doing it to your self, so the Filter on the LOE should still be run once in a while as part of "clean-up" actions on your project.
